In addition to variation in habit within the species, occasional plants have divergent forms of foliage. One collection (Canada, British Columbia, dry woods near Victoria, S . Flowers s . n ., 1 Aug 1950, UC, WIU) has older foliage typical of the species, with all newer foliage strongly flattened, with facial and lateral leaves of strongly unequal size, and with smaller cones. In light of the foliar and habit phenotypes recognized in the horticultural literature (for example, A. J. Rehder [1949] listed, with full bibliographic citations, 22 published varieties and forms best considered as cultivars), no taxonomic significance is attached to this variation here.
